Regional homogeneity (ReHo), a processed data from resting-state functional magnetic resonance imaging, provides information about spontaneous brain activity in focal areas. Altered ReHo in brain regions has been reported in Parkinson's disease (PD). We compared ReHo of 22 patients with PD in their off-medication state to 25 healthy controls. We observed(More)
Each subregion of the amygdala is characterized by a distinct cytoarchitecture and function. However, most previous studies on sexual dimorphism and aging have assessed differences in the structure of the amygdala at the level of the amygdala in its entirety rather than at the subregional level. Using an amygdala subregional shape analysis, we investigated(More)
OBJECTIVE The aims of this study were to investigate the interference of the brain activation during a passive movement task (PMT) by retained acupuncture at the ST 36 acupoint and to compare these effects between normal brain and Parkinson's disease (PD) brain. METHODS Functional magnetic resonance imaging (fMRI) techniques have been used to study(More)
BACKGROUND Parkinson's disease (PD) is a degenerative brain disorder that is caused by neural defects in the substantia nigra. Numerous studies have reported that acupuncture treatment on GB34 (Yanglingquan) leads to significant improvements in patients with PD and in PD animal models. Studies using functional magnetic resonance imaging (fMRI) have shown(More)
OBJECTIVE Functional magnetic resonance imaging (fMRI), in combination with block design paradigms with consecutive acupuncture stimulations, has often been used to investigate the neural responses to acupuncture. In this study, we investigated whether previous acupuncture stimulations can affect brain activations of later acupuncture stimulations. DESIGN(More)
BACKGROUND Acupuncture is increasingly used as an additional treatment for patients with Parkinson's disease (PD). METHODS In this functional magnetic resonance imaging study, brain activation in response to acupuncture in a group of 12 patients with PD was compared with a group of 12 healthy participants. Acupuncture was conducted on a specific acupoint,(More)
